Inferred merger-rate density ﹩{ \mathcal R }({\chi }_{{\rm{eff}}};z)﹩ evaluated at redshifts z = 0.2 (left, in blue) and z = 0.8 (right, in orange). The solid line shows the posterior median, while the colored (gray) regions enclose the central 90% (99%) credible intervals. The dashed lines represent scaled KDEs of the true underlying population.
